ECC优化的Matlab实现

说明：  获取硬盘物理序列号,用来对软件加密，vs2008工程。(HD number)

encryption algorithm, IDEA, symmetric key cryptography algorithm used in internet widly

实现elgamal加解密 在VC6.0下面(Realization of ElGamal encryption and decryption)

现在很多J2EE应用都采用一个license文件来授权系统的使用，特别是在系统购买的早期，会提供有限制的license文件对系统进行限制，比如试用版有譬如IP、日期、最大用户数量的限制等。 而License文件中的Base64或BEA公司现在是WebLo

说明：  基于AES和RSA加密算法的RFID安全机制 考虑到对国内应用最广泛的Mifarel系列标签的安全手t一级， 在建立以 MFRC500为读卡核心的RFID读卡系统的基础上，提出了一种基于非 对称加密与对称加密算法相结合的RFID安全机制。利用一1卜对称力11密算法对对称 加密算法的密钥的二次加密，做到只有特定的读写器才能拥有读写卡的权利。该 安全机制跳过RFID在开放环境中传输所面临的各种威胁，通过利少月安全性和稳 定性久经考验的公开安全加密算法对存入智能卡信息的重加密，解决了RFID所 面临的安全和隐私泄露问题 (Taking into account the most widely used domestic Mifarel series of labels t a safe hand, In the establishment of MFRC500 as the reader, RFID reader system, the core was proposed based on a based on non- Symmetric encryption and symmetric encryption algorithm is a combination of RFID security mechanism. The use of a one-Bu symmetry edge 11 close to the symmetric algorithm The key encryption algorithm for re-keying, so that only certain card reader in order to have the right to read and write. The Skip RFID security mechanisms to transfer in an open environment faced by a variety of threats, through the pros on the security and stability Qualitative time-tested public security encryption algorithm into the smart card information, re-encryption, solved by RFID Faced with the problem of security and privacy leaks)

这是用于取证中完整性检测的工具，能够有效的提高完整性检测的空间效率(This is used to detect evidence of the integrity of the tool that can effectively improve the integrity of the space efficiency of detection)

SM2 SM3 签名，验证签名，加密，解密，很好用的(SM2 signature verification C language implements very good resources for signing signature verification signatures)

使用Windows加密API的例子-Example for using windows api of encrypting

This program encodes and decodes a character using the Vigenere Square method

在不改变access文件密码的情况下，直接查看密码，数据库内容一览无余哦！-Without changing the password access documents directly view the password, database content glance Oh!
